摘要

对桉木硫酸盐浆进行无元素氯漂白(ECF)工艺参数优化，以减少AOX的生成。最佳条件为纸浆浓度10%，ClO2用量2.8%，pH 3.5，温度60℃，时间60 min, D0;H2O2用量1.25%，碱用量2.0%，温度65℃，时间105 min;ClO2投加量0.2%，pH值4.5，温度60℃，D1下时间55 min。AOX形成量为0.553 kg。Tp-1，每级0.470 kg。Tp-1, 0.060千克。Tp-1和0.023 kg。分别tp-1。与未优化的AOX地层相比，降低了23.7%。亮度和粘度为84.36% ISO, 834.6 mL.g-1。事实上，当AOX形成量急剧下降时，获得了良好的纸浆质量。为减少AOX的产生，实现清洁漂白提供了理论依据。

Absorbable Organic Halide Reduction Research in Elemental Chlorine-Free Bleaching of Eucalyptus Kraft Pulp

The parameters of elemental chlorine-free (ECF) bleaching (D0EpD1) of eucalyptus kraft pulp were optimized to reduce AOX formation. The optimal conditions were pulp concentration 10%, ClO2 dosage 2.8%, pH 3.5, temperature 60°C, time 60 min at D0; H2O2 dosage 1.25%, alkali dosage 2.0%, temperature 65°C, time 105 min at Ep; ClO2 dosage 0.2%, pH 4.5, temperature 60°C, time 55 min at D1. AOX formation was 0.553 kg.tp–1, each stage was 0.470 kg.tp–1, 0.060 kg.tp–1 and 0.023 kg.tp–1, respectively. Compared with un-optimized AOX formation decreased by 23.7%.The brightness and viscosity was 84.36% ISO, 834.6 mL.g–1. In fact, good quality of the pulp was obtained when AOX formation has fallen dramatically. These provide a theoretical basis for reducing the produce of AOX and realizing the clean bleaching.

期刊介绍： The international Journal of Residuals Science & Technology (JRST) is a blind-refereed quarterly devoted to conscientious analysis and commentary regarding significant environmental sciences-oriented research and technical management of residuals in the environment. The journal provides a forum for scientific investigations addressing contamination within environmental media of air, water, soil, and biota and also offers studies exploring source, fate, transport, and ecological effects of environmental contamination.
